Usage
Information
When you configure
keepalive
, the system sends a self-addressed packet out of the configured
interface to verify that the far end of a WAN link is up. When you configure
no keepalive
, the
system does not send keepalive packets and so the local end of a WAN link remains up even if the
remote end is down.
lfs enable (EtherScale)
e
Enable Link Fault Signaling (LFS) on EtherScale 10 Gigabit Ethernet interfaces only.
Syntax
lfs enable
To disable LFS, enter
no lfs enable
.
Defaults
Enabled.
Command Modes
INTERFACE (10 Gigabit Ethernet interfaces only)
Command
History
Usage
Information
If there is a failure on the link, FTOS brings down the interface. The interface will stay down until the
link failure signal stops.
seconds
(OPTIONAL) For SONET interfaces with PPP encapsulation enabled, enter the number of
seconds between keepalive packets.
Range: 0 to 23767
Default: 10 seconds
